+%A whole set of licenses have been written to use for this purpose.  %
+%Briefly, strong copyleft licenses do not allow for software to be modified or enhancements without
+%sharing those enhancements under the same licenses.  %
+%These ``viral'' licenses are meant to force companies and individuals who would otherwise not open
+%source to share their code.  %
+%The strongest copyleft licenses do not even allow others to link against the licensed software
+%without themselves being copyleft.  %
+%This strategy has been moderately successful, but is becoming less popular.  % TODO: cite
